What were your thoughts when you acquired them? That's always helpful to know.
Probably wasn't thinking as hard as I should have been...
I'm sure the search volumes influenced my decision in favour of investing in them at the time, thinking that there are quite a few universities that offer these courses (which aren't cheap either) and figured a small site could be developed around students either in these courses or considering taking these courses... but as I mentioned - probably didn't think hard enough about the commercial viability of the domains.
The real reason I ask is because they are coming up for renewal, and given I haven't done much with them to date, I'm conflicted as to whether I tell myself I will do something with them in the next two years or whether I should just cut my losses and move onto greener pastures.
