I have been using Vim since 4 years. I am looking forward to contribute to the open source project vim. I would like a few tips on where to start and whom to contact to contribute to Vim. Help from people who have already contributed to Vim would help a lot :). Thanks in advance. 

PS - I am not even sure whether i can post this here but finally decided to post it here as this would be the place with the most Vim enthusiasts to talk with.
