Flashing the recovery that's in ROM manager is a no no. Downloading and installing the two Gingerbread ROMs listed is still bad news.
That's it.
I use ROM Manager very effectively to manage my backups.
I can rename or delete an existing backup.
I can name a backup before backing up the ROM, back up the ROM, and have it boot back into current ROM all from the app, Basically pick a name, select ok, set phone down for 5-7 minutes, come back to phone already booted back into ROM with everything done.
I can set up ROM Manager to auto backup my Currently installed ROM at scheduled intervals during the Week (premium version).
The Fix permissions option works, same as opening up a terminal and typing it in.
You can flash a ROM that doesn't require any Gapps, and then have it auto boot into new ROM.
You can flash a ROM and Gapps with the premium version and obijohn's or LeslieAnn's wiper zips and have it auto boot into new ROM.
Everything is set up from the app, set the phone down, come back in 7-10 minutes with everything done and phone booted into new ROM.
All this and a little more can also be done with the ZenGarden recovery, not just a ClockworkMod recovery.
I wrote a sticky over at AF that explains everything.
It started out as a watch out sort of tutorial, but I am honest to a fault, so I posted just the facts.
I learned it was pretty cool for doing several things while saving time and energy.
Just don't flash the recovery, or the two Gingerbread ROMs.
The two Froyo ROMs are ok to flash as they where submitted by there developer.
