I would appreciate it Ymlong if you could maybe share any more details you have on how this system performs in practice as I've only seen the theory behind it so far.
As with any other DnD-styled tabletop RPG, expect it to be many, many times slower paced than a normal RP, especially with new players. Since I don't think you have the resources to hold a weekly Skype session (which is how I played back in the day when we couldn't meet in person), a lot of things will depend on the commitment and credibility of the player.
Going by DnD experience, a lot of things are determined by dice, even character creation. Not being able to physically see the other players you'll be playing with means you'll run the risk of players cheating on rolls, especially when dealing with life-or-death situations. The only way to solve this (at least in a non-verbal way) would be to have the GM roll all dice, which would slow down an already slow system.
Over Skype with 6 players, it can take upwards of an hour to resolve a single encounter, and that's with everyone knowing what they're doing in advance. If you're going to try doing it in a forum-based system, and have the GM roll all dice involved (setting aside updating player health, item usage, arrow usage, character movement, spell usage, mob usage and mob movements), I'd suggest you get players who are willing to wait real-life days in order to make a move in said game, and keeping the player count to 4 or below.

A general combat round would go something like this, if I were to translate it into forum posts. This is assuming you know the positions of each player and mob in the map at the time of the encounter.
Initiative roll, to determine turn order. Usually done by each player separately, but for fairness and cheat prevention best done by GM, after taking into account player skill modifiers which could add or subtract from initiative.
Assuming one of the players gets highest initiative, movement. Generally dictated by moving a figure on the board, but as we only have a text medium, informing the GM where to move. This is generally followed by an attack, which normally would be rolled by the player as well, but for fairness sake should be done by the GM.
Another GM post, detailing results of attack.
If the player has skills that allow for a second move, then they would be allowed to post again here, followed by another reply from the GM. The player's turn ends, and the next player or mob is free to move. There generally isn't time for banter, as you can tell, and most of it will be very much OOC. By official DnD RP laws, these 5 posts lasted a whopping 6 ingame seconds.

Now, that was for one player. Mob attacks will generally last one round, as the GM can simply roll the player's defense roll for them (assuming the player has no skills that can add or subtract from that, which would probably add a few more posts onto the board), but it'll generally be multiple mob rounds between actual players, which could potentially drag on the next player's turn for ages.
With 4 players, the player with lowest initiative could have to wait up to 10 posts just to have their turn. Which could be as simple as "Move A to B, then attack C", which then would require a GM's response, and so on. Not too ideal in a forum format.
How do you plan on using 3D models if you're merely doing it on a forum layout? Or do you have another site to use?
