Currently I can't send or receive files from anyone on any of my accounts (AIM, MSN and Yahoo). Is this a Coccinella thing or the fault of my Jabber server (tuff.org.uk)?
File transfers to closed networks need to go over the transports instead of P2P. So, it is very likely your Jabber server (tuff.org.uk) has transports with file transfer disabled. You can try to contact your Jabber server admin or you can give your AIM, MSN and Yahoo contact details so that I can test file transfer with you (I don't have AIM, MSN and Yahoo contacts myself).
