This one was easy for me because I've spent years toodling in Braingle's many forums.
But, when I first started on a Forum Using site it was quite a change from the other sites I had been too.
A lot more scrolling for instance.
I LOVE the Home and End keys... Page Up and Down are good, but End takes you to the bottom immediately and Home to the top in one click!
I just now noticed that I can edit the number of posts/topics per page (in Profile Settings) and that's made things easier.  In a topic with hundreds of posts, instead of reading 10, 25, etc and then having to choose the next page number I scroll through a hundred posts, THEN just hit page 2.  Better for me, others prolly like the less posts per page, I think most use the default's since topics will say Pics Page 8, and it's only page 8 on certain settings... on my settings that's still page one (I think?)
Also, with SO many topics it can be tough to find just what you want so use that search bar... priceless!!
And I use Recent Posts (next to Profile on the top blue strip) a LOT!
You can Subscribe to a topic, and it emails you when a new post is made in it, OR if you don't want to do that with tons of topics you can go to your Profile and Click on Show All Posts and it will show all your posts, including the title of the topic, with a link to Go To Post so you can easily find topics you're interested in.
Those are a few little things that I use... maybe you'll like one... anywho, WELCOME!!
Lots of nice, experienced, and fun people on here all willing to help with questions, brainstorming, and giggles!!
