I visit one called TLK goes on, which is a role play forum about The Lion King, and my username is MahewaRac.
Well, the only forum I am really active in now is Pixar Planet. I do visit the Animation World Network forums on a weekly basis, but rarely post. The only other forum I was really active in was Rupert’s Party Place back in the day. I was a huge fan of Rupert Grint… still a fan now really. Anyway, the forum closed a few years back sadly.
Rupert Grint’s cool because he’s got ginger hair like me. 
I’ve joined Gomertopia and Rebolution but don’t post as much…
Only two, hah. I’ve been a member of quite a few, but there are only two I still visit regularly besides here.
Radnet.org.uk - The DanRadcliffe.com forums
walleforum.com - The WALL-E forum, obviously. Lots of fun. Great discussions. Really nice people.
