A sale on Limnu

The collaborative white-boarding program I used for my ray tracing e books has finished their enterprise team features that your boss will want if you are in a company.   It's normally $8 a month per user but if you buy in the next week it is $4 per month for a year.   Looks like that rate will apply to any users added to your team before or after the deadline as well.   I love this program-- try it!
