The sidebar always works for a peak hour prompt, bumping or even depleting an old interest check can help, and discord is another way to let people know. (The reason why it prompts you for your email is so GuildBot can cross reference it to your account and assign a member role. Non site members — including spam bots — don't get a role and thus can't post)

If all else fails, close off the RP and create a reboot. Some friends and I have dome that with our [url=https://www.roleplayerguild.com/topics/139326-ncq-the-polaris-saga/ooc]NCQ[/url] mecha RP and it gave us the added advantage of tweaking lore, characters, and even changing GMs before we start round 2, 3, [sub]4, [sub]5[/sub][/sub].
