I don’t like it, but unfortunately, I have to put some terms of use.
My tubes and lines are made by me, on the computer, and colored pixel by pixel by me.

• You can NOT modify them, ok… yes, you can modify them minimally to make an animation, but still, they will remain mine.
• You can’t add them as they are, for your members in your membership, if you have it… You can’t resell them, or share them with anyone else.
• You can, create sigtags, web links, premades, IM stationery, etc… and then yes, you can put them on your members site, give them away, sell them… etc.
• You CAN, create sigtags, web sets, premades, IM stationery, etc… and then yes, you can put them on your members site, give them away, sell them… etc.
• Each package of tubes, lines, etc… includes a logo that you should put on your website, (if you have it) with a link directed to mine.

• You should also put a link where you use my tubes, giving me the corresponding credit.

I am not going to extend more, in short, we all know what to do and that we should not do what we would not like to be done with us. It is about respecting the work of others.
In any case, I reserve the right to change these points, if I find it necessary.
