yes a did, a few months ago. I followed the instructions from the pdf uploaded by cheegii.

I don't think you need to pay. If you add some useful posts in ths forum you get awarded some "coins" or credit it seems.
I think cheegii is an admin on the forum (he awards coins). he may be able to help out.
