Yahoo as implemented limits on what you can spam in rooms, to stop BOTS. Many many TD's have been banned because of this.
Take it from me, there very many TD's that have been banned in this way, across all types of leagues. Only thing you can do is make a new Yahoo ID. BUT i found this works.
SHORTKEYS:
Open Shortkeys. Click on OPTIONS/ PREFERENCES/DELAYS. Select "Allshortkeyuse". Type in window 7000. Click on APPLY then click OK. Dont make giant spams. And if spamming pairings remove all spaces between lines and at the end.
KEYTEXT:
Keep your text all in one block ( paragraph ) !
not seperate lines. Limit your rules to 4 lines ( i have heard it can be more ) But i use 4 and it works perfect. Again remove all spaces between lines and at the end. I had to re-write all my tourney rules.
Also to test your settings and new rules try them out in an EMPTY room with a ID you wont mind losing if it goes wrong. Please only test in Empty rooms.
