MX823 gave some great advice... but im gonna add to it:)
Anyway.. keep your speed up. Im sure you know since i see you ride a 125. But its very importand in the mud. Once you stop it takes awhile to get back up to speed. So DONT CRASH! :p j/k try not to, but its not imperitive. Umm.. dont lock the front brake?;) thats just common sense... When ever you manage to find a straight, speed up! keep the mud off your tires, and the best way to do that is... *gasp* spin them!:D Also, believe it or not, the faster you go, the easier it is. Let the bike move under you, dont try to make it go exactly where you want it to. Just point it in the general direction and it will get there.
BTW - who says spinning out of a slick corner isnt fun?
