Yes we know that this is a site wide issue and its not just this group, this was merely posted to help clear up any confusion from members who were not aware and to give them advice on how to submit. [link]
AND it does seem that the DA Admins know about the issue.
As some of you are aware of we are currently experiencing a glitch with submissions that does not allow our members to submit to the group. Several of our admins have sent reports to the help desk and have not heard back yet. We are very sorry if you experience this glitch and we will do everything in our power to help you submit but please keep in mind we have no control over it. There have been lots of glitches here lately on DeviantART, I know I have personally experienced a few and I know I'm not alone; so hopefully the issue will be resolved soon.So if you are having problems submitting to the group please make sure you have done the following first:
Make sure you are a member of the group first!
Make sure you are submitting to this folder [link]
that is the only folder we allow members to submit to!
Make sure you are clicking the submit to this folder button in the folder listed above. For help locating that button please refer to [link]
If you can not submit through the actual folder, try submitting through your deviations page. To do so go to your deviations page, click submit to group, type our groups name MLPFriendshipIsMagic into the type a groups name box, click on the drop down menu and select the "Stable-Submit Deviations Here" folder, then click submit. For more help please refer to [link]
IF none of the above works, do not submit a comment on the groups page
instead send the group a note with a link to the deviation you want to submit and one of our admins will send your deviation an invite to be included in the group.
