Hi @Savage GT
The quickest way to get to flag a problem and hopefully get an answer, is to PM a Mod or Admin with your query.
Which thread specifically (please copy the link to this page) are you trying to reply to?
If it's a locked or sold thread, you will not be able to reply - e.g. this one below
However, if it is not locked/sold - e.g. this one below
You should be able to reply. If you could please try and post on the second link, just any message will do, if it works, I will tidy it up.
I have checked your profile and there is no reason there that you should not be able to reply. I have also checked the permissions on the forum sub section and cannot see an issue there. It's not impossible there is a browser or caching issue. If you are still unable to post in the second thread, then suggest trying an alternate browser briefly - so we can rule that in or out. Thanks.
