Hi Carlen,
Thanks for posting.
Are you talking about the Volunteer Sign-Up Sheets plugin, or the Member Directory plugin?
At one time I was working on front-end submissions for the Member Directory plugin, where users could submit their own listings, with approval from Admin before they get published. For the Volunteer plugin, there was nothing similar… people can sign-up from the front end, but sheets need to be created from the admin side.
Either way, I have no current plans to work on either of those, as I’ve become far too busy with custom development projects where I can actually earn almost enough to feed my family. The free plugins, even with the low cost add-on extensions, are lucky if they bring in $20 each month or so… not even enough to cover the time I spend on supporting them. So, right now, any further features or extensions for those are extremely low priority unless there is enough interest or up front funding to cover my time.
The plugins are all open-source, though, and, as such, any developer is free to create extensions for them, or to modify them and fork them into their own plugin. If you have working knowledge of PHP and how the hook system works in WordPress, or know somebody that does, it wouldn’t be that difficult to create your own extensions. My free plugins have plenty of action & filter hooks in place to allow them to be extended by other developers.
