Logo for a cutting edge sports management software startup

Atomic Leagues

We are building online league and team management software that allows sport teams, leagues, and players to manage their web presence with customizable team, league, and player sites, track statistics, etc. We are looking for a logo that conveys the sense that Atomic Leagues is fun, social, and next generation web.

Initially, amateur or school baseball leagues/teams. Eventually, management software for a variety of sports. Users will include coaches, players, parents, fans, umpires, etc.

Brighter colors – maybe red, orange, yellow. However, please feel free to experiment with colors! The logo does not need to match any existing color schemes or brand, I will be styling the rest of the site around it. If possible it should look good on a white background, but this isn’t a strict requirement.

Tagline - "powered by your team" This doesn't necessarily have to be worked into the logo, but it would be nice to see examples where it is.

A few words that describe what we are looking for:
Clean
Crisp
Edgy
Fun
Comic-Bookish (is that a word?)
atom or power

Please do not use any stock images or clip art in the logo.

The logo should work both in small and large-scale ranging from business cards to full screen presentations as well as on web properties and printed material.

On being awarded the prize the logo will need to be supplied in the following formats:
• All color formats and mono formats
• Jpeg
• PNG (with Transparent Background)
• CMYK format - SVG and PDF

A couple of examples:

At this point I am open to anything. I am also looking for a trusted design resource to pitch other things to. Have fun and definitely ask any questions you might have - thanks!
