BBO
It’s tough to play a relay system on Bridge Base Online; you need to do a lot of typing.
The old Windows BBO client came with a program called Full Disclosure, which allowed pairs to fully document their method.

The simple Windows exe file bidedit.exe starts Full Disclosure. Just unzip and run it.
For Scamp users, there is also a file called Scamp20.bbs.
It is a simple text file with about 8000 lines of text, detailing nearly every relay sequence.
Bidedit will open this. You can modify to suit your own agreements (Settings – Editor)

All good but it only works with the old Windows version of BBO, which is no longer supported.

To use your documented system with the current web-based BBO, you need to install another program, BBO Alert by Stan Mazur. This works best in Chrome. Google, or follow this link:

Once installed, BBOAlert will appear as a [tab] when you log in to BBO.
When you type an explanation of a bid in a new sequence, BBOAlert will remember it and the explanation will pop up when that sequence occurs in the future.

However, we don’t the App that way. Instead, we open Scamp20.bbs with Notepad, Select and Copy All (Ctl-A, Ctl-C) then [Import] to BBOAlert. If something is wrong, or needs to be added, we do that in Full Disclosure. So data only travels one way.

We choose [Confirm bids] under Account options to make sure the explanation is correct, then away we go. Note this is a bit unfair because I can see what my bids mean, so I won’t make a shape-showing error. Still, it’s usually deemed acceptable to consult your own system card on BBO.

Bidding Practice on BBO
You can’t learn relay at the bridge table. Better to go to [Practice] [Start a Bidding table]
Use robots as EW, load the system into BBOAlert if you wish and away you two go.
Use [Deal Source] [Constraint Set 1] restrict dealer to N or S, chose minimum HCP.

You can also try [Practice] [Start a Teaching table], load the system and plonk yourself in all four seats or – better – rent some $1 robots as EW. Again,
Use [Deal Source] [Constraint Set 1] restrict dealer to N or S, chose (high) minimum HCP.
This time, there will be cardplay, which you can curtail.
