Plus, I want points for having said right off that the 'problem' is no big deal for me because I get adequate info via My Replies & Recent Posts.
OK....so it's not a problem then for you, and for the other person [OP] it's actually not a bug either....as it's how things are intended.
What frustrates most is when someone explains the status quo he's labeled a Stardock fanboi, but anyone seeking change or revision is considered an erudite master of the sublime.
As with MOST forums 'true functionality' relies on frequency of attendance.
If you cannot find appropriate responses in 'recent posts' then you yourself have not been here 'recent' enough....
Re 'forum structure/architecture', if the forums were more segregated and fragmented [stagnated] it's not just ease of access to spam to consider...but also the supervision of general user conduct.
Stardock's sites are moderated. We keep an eye on things [eg. online bullying is a modern social blight]. Flaming, personal attack, etc.
Getting around on the forums may feel 'clunky' to some ... but the sites are sociable....
