There are some contexts where it would seem nice if the thread starter could update their first post for an indefinite period of time. Namely, when someone would like to share something forum-topical (list of links on a subject, some code, whatever) and keep that something updated. I've seen this type of thing being done in various forums, and found it useful. However, I haven't given the pattern and implementation pros/cons much thought. Is this something that is supported by XenForo or an addon to said? Is this something that has been considered for this forum in the past? I think there could be a "promotes publishing-by-one vs discussion-by-many" argument against it. I'd understand a: "maintain it elsewhere and, if topical, just post a link here" approach. On the other hand, maybe it is something that others... including LWM et al... would like and find practical.
