I am fro iit gandhinagar, we are evaluating this CRM to build up our public relaion database.

I couldn't understand one thing here that file storage in enterprise edition is 500MB/organization. that sound like how many users I have, I will always get only 500MB default which is very small size for our organization. 

Please clear my query ASAP

please tell me one thing that is there way by which you can extend our trail period as our evaluation is not complete yet.

thanks
