This is what I'm thinking for the updated Review GUI (let me know what y'all think):
Made some more changes / updates after testing with Furling:-Opens either the Forms or Review GUI, depending on if a client is host or not.
-The Review GUI now automatically updates when choosing the category tabs, so you can easily find new, pending applications.
-Applications can now be reviewed by simply clicking on a player's Blockland ID / Name in the App list on the left.
-Automatically resets GUI methods upon disconnecting from a server, to make sure the appropriate (host/non-host) GUI is opened each time.
Still need to work on:-Choosing a response to applications once reviewed
-Fix the issue with messageBoxOk (still not sure what's causing it)
-Work on adding a spam filter for server commands (?)
-Reapply limits and blacklisting
