Hi Tharaka, Really? I could have sworn there was a 16th April deadline! I haven't had an email with your request ( https://issues.apache.org/jira/secure/IssueNavigator!executeAdvanced.jspa), the dev-community gets spammed with everyone's projects proposals, and there have been a lot. I just found yours at (for anyone else looking for it): http://www.google-melange.com/gsoc/proposal/review/google/gsoc2012/tharaka/1
The ASF protocol is to create an issue on JIRA (link above) and then do one on google-melange, it allows a link for searching and keeping track of things. I think there are other reasons, but I forget them, anywho, my sincerest apologies, I'll review it in the morning.
