WordPress itself can handle lots of traffic if scaled correctly. However, if you're looking to do lots of custom features that don't have WordPress plugins for and require custom work, then you're probably better off with a custom product.
Not sure what this means. Like the amount of links? or total uploaded files?
Yes, total uploaded files in post. For example, one can attach only five images in the message.
Oh, maybe you mean editing the post in HTML mode like some forums have, that might be neat.
Maybe that's what I mean. For example, can lead editor xenforo -
fyi, This information is already on the profile page of each user.
It might be nice to have a User Statistics page with a table displaying this type of information.
I delete it there. Quite a strange place to display ip addresses. I think that it would be wiser to display them in the admin control panel (ADMIN CONTROL PANEL - MANAGE - USERS).
What about - 'Guests posts in topics do not appear immediately. Guests need to refresh the page. It seems to me that this is not good'?
Guests must refresh the page topic, to see new messages.
Those who logged - new messages appear immediately. No need to refresh the page to see the new messages in the thread.
It would be better if guests also would not have to refresh the page.

It's definitely possible, as the theming for NodeBB is quite flexible. Earlier this year, I started working on a blog-like theme, based off of some designs by Randy M. Daniel: http://www.randydaniel.me/nodebb-theme
I didn't quite get it to the point of publishing it, so if you're interested in picking up where I left off, feel free!
