Verbal and written both. For verbal we can visit ivisit and for written I was thinking of something like this:
http://www.bbc.co.uk/dna/mble/F2712586?thread=3752693&skip=1220&show=20 . I am melearneng in here and I practice my writing by posting messages to my virtual friends. Only disadvantage of that forum is that I don't know whether I wrote the right sentence or not. I was planning on inviting all my my friends from that website to join here. BTW, I loved the link you have on the main part of the site. Can't believe I missed that. Is it ok if I ask you some quick/small sentences in there for a quick correction. That would be the best thing for me...
Downloading ivisit software is very simple and you can chat the same way as MSN or yahoo messenger.
