Level Up Meter
Doesn't work (or I have no clue how to set it) - as installed it does not work, maybe there are no default settings, and the instructions are not sufficient to enable a novice to make it work.
Edit: Tried it again, made every possible change -- and nothing. An absolute did.
Automatic Acronyms
Doesn't work. Acronyms show up underlined, but the definitions/explanations do not appear.
Flip Thread
It has a bug: on multi-page threads, sometimes the thread opens on the first page and sometimes on the last page. I also received feedback that the screen may freeze :(
Simple Search
Minus one star for the following bug: If you put a space in front of and after the word "Search" (i.e., " Search "), in order to make the button a little wider, the plugin does not work at all.
