Is it possible to update a cartridge that has already been submitted? I couldn't find any option. I know these are supposed to be actual cartridges so maybe there could be an "Issue Recall m( )m" button.

I asked the same before :)
You have to submit another time then note the [#xxxx] number you will have for your cartridge.
Then you edit your initial post and put the number in the place of your old one.

Thanks! Yeah I ended doing this. I guess I'll just have to share the forum post url instead of the direct link to the cartridge.

I've updated the submission system to make this easier. If you select 'Update a Cartridge Thread' from the submit page, it will ask you to select the thread you want to update and automatically insert the new tag at the end of the process.

zep, wil this submitting process allow the favorites and stars to remain or it will be reset just like before?
