Gonna be quick cause I am on my phone with no computer available at the moment.
Firstly, if you want so badly to ask those questions, why didn't you just go to the AGM and ask them?
Second, membership has grown year on year for many years now. So not sure what your no growth stat is based on. Have a quick look at the link below for a few figures.

A few key points from the article:
1. 11% growth in 2011 against 2010 numbers.
2. Since 2003, membership has increased 78%.
Please feel free to comment on the above and tell me we have had no membership growth.
