BBC News website reader Christopher Williams, 21, from Oxford, is a member of our UK interactive panel.
He took part in Saturday's Make Poverty History rally and will also be participating in Wednesday's G8 protest in Edinburgh.
He is sending updates from the protests throughout both days in text and video, using his 3G mobile phone.
CASTLE TERRACE, EDINBURGH, SATURDAY 1800 BST
I've been around most of the course now. I just passed through Princes Street.
The number of people along the route was thinning out for a bit before we reached it but it has been a lot busier since.
It's very lively with people playing music and dancing, and there are others simply lining the streets cheering other marchers on.
Some are also taking a rest along the way.
I spoke to a steward nearby who said she had seen no trouble overall.
Others I spoke to were saying the fact that the march is so behind schedule and moving so slowly is a good sign because it means there are a lot more out here than expected.
It's been a great day. There's a real feeling of solidarity here.
Perhaps we can only achieve a small amount by turning out here today, but the G8 leaders certainly can't ignore us.
FOREST ROAD, EDINBURGH, SATURDAY 1645 BST
I had to stop to charge my phone, so I found a pub that allowed me to do so, and got a quick bit of refreshment while I was at it!
Hence the delay and the detour, but I am now back on course and approaching Princes Street, where the majority of the protestors are congregating along the route.
Susan in the Isle of Arran, Scotland, has emailed in to ask me how many people are at the march today.
Someone told me along the route that there are more than 120,000, but apparently official figures put it at 200,000 so that's obviously great.
There's a very positive attitude along the route, although at the start people were very anxious to get going after the long delays.
START OF MARCH ROUTE, EDINBURGH, SATURDAY 1510 BST
We are finally heading out onto the main route now.
It's a good time to answer some of your questions you have sent in.
In response to a question from someone calling themselves Aid in Bristol - why am I doing this - I am here because I have always been interested in development issues, fair trade and issues surrounding poverty and climate change.
Initially when I heard of the Make Poverty History organisation and this march, I thought it was just another slogan.
But I genuinely believe this is a unique opportunity to make at least a small change.
Also, Andy (who did not say where he was emailing in from) asks if I really think I can make a difference.
I believe I can. There's still time for everyone here to make a difference and influence the decisions that will be made at the G8 summit next week.
It is our chance to show the leaders and the rest of the world that we want to see real change.
The fact that there are so many campaigners here from all around the world just illustrates that.
THE MEADOWS, EDINBURGH, SATURDAY 1345 BST
We are edging forward slightly.
We're well behind schedule, and the organisers just apologised to us for the delay.
Maybe there are too many people here, but that's obviously a good sign!
People are blowing their whistles periodically in huge bursts of noise.
The biggest one just came when they announced that the white band of people around Edinburgh city centre had just been completed, with the first wave of people now returning to the Meadows having completed the marching route.
THE MEADOWS, EDINBURGH, SATURDAY 1245 BST
We are still waiting to go.
There are so many thousands of people here at the starting point that it is taking a long time for us to move out onto the main route.
We expect to be on the move soon towards Prince's Street and will then form part of the white circle around central Edinburgh.
THE MEADOWS, EDINBURGH, SATURDAY 1100 BST
After an overnight bus journey, I'm standing at the starting point, the Meadows, of the Make Poverty History march in Edinburgh.
I'm surrounded by several thousand people, almost all dressed in white.
They all seem to be wearing white wristbands as well.
There are bands playing and guests making speeches.
Everyone is in really good spirits. It's a really positive atmosphere.
We're ready and looking forward to the day ahead.
