Well, .com is commercial, this isn't exactly a commercial site. By your logic, Lucky, we should go with .net because this is more of a "network". However, I can assure you that most people on the internet (me, for example), don't care about the TLD, as long as you have one. The most used, and therefore the "best", is obviously .com due to it's popularity. And, I would go with .net as your secondary. But, in the end it doesn't matter, just snag the .com if you can. Now, on topic... This domain, I agree, is much too long. I say move away from Enigma completely and start with a new name, (and possibly design?

) so we can find a nice short domain, and then keep that.
Remember, switching domains this much isn't good. I think this is something like our 3rd domains, and I still remember us as the Enigmachs. You loose a lot of SEO leverage everytime you switch, so let's make this the last switch, move away from Enigma, and get a good domain. Take time in considering this.
