What I want to do:
I want to limit number of posts users can submit (per usergroup) either:
How can I do that with minimum code editing? May be there were some snippets done for that already?
Thanks.
Is the user going to be a logged in user on the WordPress site or is it going to be based on something like a specific email they use in an email field? How do you distinguish users?
This customization would require code. You'd have to use the gform_pre_render hook and write custom code to see if the user has already submitted an entry within the last X days/hours/whatever by querying the entry data.
Here is the gform_pre_render hook documentation:

Note what you want to do we don't currently have any code samples.
Is there a way to get the time of the last submitted post by a user?
I can just subtract last post's time from current time and then if it is smaller than predefined ammount - hide the form and display the message? I think it is the most economical way. Is that possible?
Yes, you'd have to query the entry data. I'll have to get one of our developers to look at this and see what you want to do and come up with a code snippet. This may take some time as customizations such as this are outside the scope of standard support.
Hi Octavian,
Paste this code into your theme's functions.php file: http://pastie.org/1721866
Make sure to update the code per the inline instructions. Let me know how this works for you.
David,
Is there a way to edit your code to limit the number of submissions by IP instead of user id?
I've recently had a spammer fill out a form on our site a hundred times in a row.
Very frustrating.
That code could definitely be customized to do so. But if you aren't comfortable with code you may need to get a developer to assist you.
Another option is to consider using captcha on your form. Or try the Gravity Forms v1.6 beta release which has built in Akismet anti-spam integration if you have Akismet activated.
Used David's code as an inspiration to write the function/filter necessary to prevent duplicate submissions from the same IP address: https://gist.github.com/1187600
Thank you Joachim!
