Even events that are not full being bumped every 30 minutes is ridiculous. Here is the biggest problem with the TTT....
Someone posts something of importance to get the word out, then someone TTT's a post to move theirs up...now the relevent thread shows there is new info to read, but the TTT's are now in front of it and NOW THE POST IS ON PAGE #2 or #3 in the matter of a few hours!!!
***Maybe you could set it so new posts go to the top and stay until a new post and all subsequent TTT"s come after any new posts.
***Better yet new posts go to page one and TTT's go to page 2 and TTT's can be bumped to page one once per day.
***Or sticky all new posts for a day or two then go back to idea number two.
*** Or...I could go on and on......lol.
