not really fit for me.

I  use permlinks (e.g.  Mermaid diagrams), so 2000 characters are not enough. URL-shortener is not a good option on chnging these links so either  I need more message length or a discord intgrated URL shortener adapted for changes.

 “message Length greater than 2000 characters”is the only feature that I really need.
"User-Defined Serverprofiles", “Colours for discord-schema” were nice but not needed. 

so if there would be a single buy option for message langth freater than 2000 character or a new Nitro basic or Nitro Text basic(an Variant of Nitro Basic) which will grantthis.

My buying limit is max. €4,50 but not €9,99 for full “Nitro” .

So if there is no cheaper opter for more textlength, i will use only discord free for all time !!!
