We all are aware that in the discord server there are commands which are used to display specific links. Some of the commands which provide guide links are helpful for new players. Similar things if made in game also might be helpful to non-discord users. I think of two ways
First way creating the specific command for some specific need.
List of in game commands which can be applied in this idea:
From discord server (There are more commands just mentioning those who are more likely to be useful for gameplay):
Bcc : Bug catching contest guide
Legends : link of legendary mega thread
Regionlocked : region locked megathread
Restore : restore pokemon megathread
Notcoded : link of not coded thread
Rules : link of rules
pstuck : Pokemon stuck in party thread
Htasa : how to access specific area
Sinnoh : sinnoh quest guide link
Gs : general support sub forum link
Guild : guild sub-forum link
Counterparts : Pokémon Counterparts - Pokémon Revolution Online Wiki (prowiki.info)
Second way
Usefullinks : I think useful links forum page can be made and make things easy just by adding one command which shows a link of that forum post which contains all important guide and forum links. It might even be easier to manage
Help command
Help : In-Game Commands - Pokémon Revolution Online Wiki (prowiki.info) shows this link to make new people aware that these commands exists
