While it is not an issue, like most clubs and forums, there are certain regulations, and this one is particularly stringent regarding new members. It would have been advantageous for you to review the regulations, as this would have provided you with a preliminary advantage. However, as previously noted, there are specific activities in which you may not engage until you have made 30 valid posts and maintained membership for 30 days.
Administrators reserve the right to discount posts they consider invalid; thus, superficial responses or trivial comments aimed at rapidly increasing your count are unlikely to succeed, as they will likely be noticed, leading to their removal from your total count.
Merely a matter of exercising patience, engaging when possible, and appreciating the existing content on the forum that captivates your interest.
