I think that you don't see the announcement at the beginning of the forum.
"You may have to register before you can post: so please send a request to https://twitter.com/#!/gtechpedia with genuine email and twitter. Sorry, we do this system to eliminate the spammer."
for the time being, we closed registration system (it was not error).
We do this because so many spammers and we do not have much time and energy to handle it. So we try to eliminate them with manual register from my hand. So please send the correct data such as your email, real name.
Moreover, all our addons are free. I really hope for your understanding and your patience. We always try to help you as long as we are still capable.
