BTW sorry for little off-topic, but why there is no mailing list for developers? Where the heck is the unix nature in all those "Smilies" and "BBCode" ;-) ? I even can't attach a file in old, good way :-P.
Bye. |

Looks good; I'll wait for Brady to look it over.

Well, I'd rather not go into all the reasons, but we do have a way to attach files - in the bug tracker. And the BBCode and smilies can be disabled per-post.

| I like it! I'll probably want to change it a bit so that Gauge's don't get set as unknown, but that's about it. I wouldn't expect it to be included in our next release (which should be *soon*), but hopefully the following one. I've started bug#419 to address this issue. Thanks for the patch! |

I thought about it too, but I was probably to lazy to do it :P.
> Thanks for the patch!
No problem, BTW thanks for Netmrg to you all! |
