boardhopper: thanks for the info, i fixed that now. there's so many things to update when i release a new version that sometimes i forget a little thing like that.
rshaven: i would estimate that 5.1.0 will be done in late may or early june, but no guarantees. if you check the manual, only a few files were changed in this update. index.php was only updated to change the version number, so it's really only 5 files updated.
