Wasn't sure if this is the best place to post this but couldn't see anywhere more suitable.

As LimeSurvey is open source is it legal to use the source code as a starting point to create an end user survey creation tool to be used as part of a service for commercial purposes?

I have a friend currently working on producing something similar from scratch however it is possible that LimeSurvey would be an excellent platform to begin from saving a lot of time and effort.

I've read the GNU but as far as I can see this doesn't cover this particular use of LimeSurvey.

Thanks in advance

Yes, totally for the code source. For the name : it's a registered trade mark, but you still can use on admin page. You don't have to advertise generic survey services.

But you can use your own services name and use on backend LimeSurvey.

As long as you do not redistribute the code I think you should be fine, as Denis says.

The question was posted more than four years ago. Let's hurry up ;-)

If I use a piece of software that has been obtained under the GNU GPL, am I allowed to modify the original code into a new program, then distribute and sell that new program commercially?

You are allowed to sell copies of the modified program commercially, but only under the terms of the GNU GPL. Thus, for instance, you must make the source code available to the users of the program as described in the GPL, and they must be allowed to redistribute and modify it as described in the GPL.

These requirements are the condition for including the GPL-covered code you received in a program of your own.

Are you a student conducting a survey? If yes, tell me why you use LimeSurvey?

You can redistribute source code :).

No doubt, but then it gets a little bit more tricky, doesn't it? As long as you run it as a SAAS you don't have to worry much about the GPL, but when you "sell" your software built on LS you must redistribute your source code under GPL as well, right?

You of course, but for others it might not be that clear.
