I don't have vote to close privileges here, but wanted to flag this question as off topic. Simply because it's not in the scope of this site, and just asking for an external website.
However, the three off topic options I have are:
Questions about software development are off-topic here, but can be asked on Stack Overflow.
Questions about pre-release software are off-topic. For more information, see Can we ask about iOS 7 and OS X Mavericks? and Can I ask about not-yet-publicly released OS?.
This question belongs on another site in the Stack Exchange network
Neither of these applies, and unfortunately I can't add any custom close reason as well. The only option I have now is to use a custom moderator flag, but as of late, closure flags are not shown to moderators and go straight to the review queue—but when using a custom flag I'd overrule this and cause additional workload for mods, while the community could handle this itself.
Would a more generic off-topic close reason make sense?
