so you are the owner and the builder of this site
http://www.bctalkaccountpricer.info/ ??
great,and also you have no wrong to wrote it in java,very good site,thanks. and i wanna ask you,how accurate this site to estimate btalk account price in percentage?
It is probably not all that accurate. What it mostly is good for is checking potential activity and addresses that the user has posted.
It seems to be still accurate, because I saw someday a trusted member selling accounts based on the price given by the estimator. I use only the tool to get my activity, and even that is still really cool

!
I have a suggestion. Why not create perma-links, so someone trying to sell his account could put a link to his analysis in his signature ?
