I didn't realise I'd have to hold off posting until I 'understood' the forum?
Take this as advice from someone who came on here guns blazing...and got their ass kicked a LOT harder than you're getting now..
Sit back. Enjoy. Read. Post.
And....avoid reacting to criticism of your posts.
Your opinion is your opinion. Fine.
But understand that posters here will at times dissect your opinion.
And they'll engage with your posts.
They won't necessarily agree with you. Just as you won't agree with their posts. And we will not always be polite... or indeed dignified..
Don't take it personally or to heart.
If you can remain objective..and not take yourself seriously...or anyone else seriously....then maybe you will find it ok here.
