+So, I now have a prevalidated (for now) account over at the [Super Dimension Fortress (SDF)](https://sdf.org/). 
+I'll most likely validate it later, but not right now. 
+In this post, I'm going to go over my initial experiences and my thoughts about them. 
+
+# Initial Signup Process
+Anyone can start using SDF by making a free account, and there's multiple ways of doing so. 
+There's a simple web form on the SDF website to do it. 
+Other methods include connecting to new@sdf.org using either SSH or Telnet (either works)
+
+I used the SSH method - though my initial choice of when to try proved to be wrong, as the one time it didn't time out it disconnected me very early in the process.
+Anyway, when SSHing to the system you'll get a series of prompts that ask you questions about your new account. 
+There's the obvious ones about username/password, but it also asks you for some details (name, email, and zip code) and isn't clear if this is required or expected (I don't think it is)
+or how the information entered will be used and displayed. As such, I only entered my name but am happy to enter an email if needed (I do not have a ZIP code, though. Not American, you see?)
+
+If you exit this user account creation process (two methods are saying N to the final 'are you sure' about it or trying to use an already-taken name) you get dumped into a basic command-line menu.
+The menu's prompt is 'FEP Command' and while this seems inconsequential, it is in fact a reference to a completely different type of computer than the UNIX and Windows-based systems that are currently dominant.
+In the 1980s and early 1990s, there were companies that made Lisp Machines, which were and still are very different to modern systems running a UNIX-like or Windows. 
+On these systems, there was a Lisp processor, but in many systems the Lisp CPU was unable to boot the system standalone, so there was an additional processor (or for the later ones, something specially integrated with the main processor) to bootstrap the Lisp one with the rest of the system.
+Symbolics systems, in particular, had a Front End Processor that perfomed this task (as well as other things like handling full system crashes).
