-As for the searching issue, well, i think it's not much of a problem, when someone searchs anything on this site, it's always hard to find what exactly you were looking for.
But if someone finds your thread as it is titled now "разные вопросы по глаголам", she/he will get a better image of what it is included in it(between the other numerous search results)
Also when MR's search engine finds some results, the word that is searched will be highlighted in the posts, so one can quickly overpass the un-required posts (however she/he might find another interesting question while finding her/his main question)
It just looks like some kind of dictionary now. Russian Verbs thesaurus.
And i would suggest if anyone wants to find her/his main question on this site, it's much better to search through google's engine at MR's domain.
Then one can find the exact page on this site!
Anyways, i as a learner say, this helps me much more than how it was before.(but everyone can have their own individual idea)
-As for the new questions, you can always check "Activity Stream"/"What's New?" To be aware of new questions/posts and continuous discussions!
