Hi there and welcome to the forum. There is a thread about past expos that may be of some help. Not too sure how to post a link but if you use the search function and type expo you should find it really easily. also on there is a link to expo website if i remember.

We went to three this year with varing usefulness but i would say go to as many as poss, spend as long as poss, and talk to as many people as poss.

This is a great place to ask all your questions and search old threads as lots of useful stuff in there.

Hope this helps, Helen.
