I just thought of this, don't know if it'll make a big difference but it could help to make PF more newbie friendly. At present the "Mentor" labels don't indicate the specialisation of the mentors, such as whether they're math/physics/bio/chem/etc. mentors. Perhaps if we included a second visible tag below the "Mentor" tag stating the specialisation of the mentors, forum newbies would know who to contact for help on certain threads. This would also help reduce a lot of misdirected PMs, but may in turn invite more PMs. Just a thought. What do you guys think?
