I disagree.

Issues that were extant then, unless systemic, are not likely to be issues still extant after 9 months. And, if systemic, it is reasonable to assume the thread would have been bumped more than once in the last 9 months.

Given people tend to read from the top (oldest) until they find something they wish to comment on, the result is generally to have OLD, PROBABLY NO LONGER RELEVANT information bumped. Which can, as has happened in the past, lead to members using the OLD, NO LONGER RELEVANT information as a launch point. Which can easily, when the information is OLD and NO LONGER RELEVANT, result in real problems for those members.

Starting a new thread avoids most of these issues.
