Where does one post questions about possible VSX errors, such as discrepant positions? I thought I might find it in a VSX faq, if one existed.
There is no VSX faq, but if you find discrepant positions you can revise the entry in question (log in to VSX and click the "Revise" link on the Detail Sheet of the object). After moderation your revision will then be promoted to the live database.
Thank you Patrick.
