Entry #16 and #17: I really like what you've got going on here. The only concern I have is that the "T" and "C" letters that are conjoined look like a backwards "G". If there is anyway to tweak this, I'd be interested in seeing your ideas. Also...though the background for the finished logo needs to be transparent, please use a dark (charcoal) gray background to show how this will look on the website. Thanks for your work!
Entry 30, 31, 40, 41, 42: I really like what you're doing with the icon here. The concept of the "power-on" icon is nice. I would like to see what you could do with it in different locations (like the left side of CTCHELP.com). I prefer how the icon looks in 30 and 31 but I prefer the overall look you were going for in 40 and 41 (esp. the size of the icon and the separation of CTC and HELP with color).
We really love entry #100 but could we see it with a dark charcoal background and white letters instead of grey. Might have to change the shadow color to white as well.
