Hi lynius,
Thanks for your suggestion.
The mod team is always just a click away, you can click on the "Report" button on any post and fill in a brief description of the issue/your request in the field provided. Whilst usually used for reporting spam/inappropriate posts etc, we have no objection to you contacting us this way should the need arise.
This sends an email to several mods and admins and there's usually several of us around pretty much 24/7 to help.
In terms of your current query, mods always try to leave threads open and available to members wherever possible. Any thread showing as closed was no doubt closed for a reason, namely to protect members from spam, abusive language or a request for a stake from an ineligible applicant etc.
If you'd like to briefly describe which thread and what you'd like added, one of the mods will take a look for you. Obviously we will only add things to a closed thread or re-open it only if it is thought to be appropriate in clarifying a situation or in exceptional cases. Normally a closed thread will remain dormant and cannot be added to.
You can pm either myself or our Community Manager Ingrid privately if you prefer.
Thanks again for the suggestion, shout if we can help further at all.
Best regards,
Bart
