[Weepy]

Usually, from experience, sponsors are religious about their logos. Editing them at all besides resizing and coloring (as long as it's a one-color logo such as Motorola's or McDonalds) is taboo.

You can usually get digital files of your sponsor's logo if you emailed them and requested it as long as you explain yourself.

Also, you may not want to sell anything with your team's name on it if it DOESN'T have their logo on it.

Whatever you do, it's best to talk to your sponsors yourself rather than ask us. Most companies have their own specific guildlines, such as FIRST.

Hope this helps.
