For my 4th batch I decided to do a RIS.  My question is when/if I need to re-pitch the yeast or just give it more time.  I brewed this on 12/26 and used White Labs 07.  I was getting some massive fermentation by day 2.  Good thing I was told to use a blow-off tube!  With the cold temps lately I've been using a warming belt, but can only get the temp up to 60-62.  White Labs says the optimal temp should be 65-70.  The OG was 1.090 and when I checked it last night it was 1.030, so it making some progess. 

Should I move the carboby to a warmer part of the house, re-pitch or just it leave it be for a few more weeks?

Thanks Splash.  I racked to a secondary, got it off the basement floor and wraped it a towel.  Given my work schedule it probably will be forgotten about unitl March or April.  How long can it sit in the secondary?  I assume I still need to wait until it gets to around 1.010 before I bottle it.
