It would be super-useful for resolving issues

• Ad creative
• YouTube text
• i18.properties

Something like https://nomadlist.com/open

When the bot is ready, it needs some promotion. I don't want to pay money for it (yet), so just looking for a places to post the links and articles.

Show a welcome message with some info for new members joining a group. Admin rigths may be required

It should read all the transactions for a given chat, group them by currency and sort (desc) by the number of transactions. Then N top currencies should be returned. 3-5 maybe more, need to check that in different clients.

A place to share feedback

Should be fixed by #35. A new step between currency and particpants with "remove keyboard" flag.

It looks really weird and should not happen. Users will think the bot is not working at all!

When the bot is added to a group, it must clearly declare what data will be collected and used.

• Welcome message should ask users to invoke a /reg command
• Reg command should be processed and users should be saved into "members" for this group
• If the bot sees new members (admin option) it should ask them to register after they are added

In private chats, it should tell users how to use the bot. In groups, it could be just an alias for /help.

• Group sizes
• Who added
• Group last active
• Languages (language code for users)
• Transactions, counters

As a Tyzenhaus bot user I want to be able to add the bot to the group to start tracking group expenses. Basic expense tracking must include support of:

• Single payer
• Multiple users being paid for
• Currencies
• Purpose (text)

I want to be able to ask for my debts stats at any time.

Check migrate_from_chat_id

…the value is included in the token.

• /lang shouldn't have any state
• /expense should check user ids on actions
• /expense should not allow zeros or empty list of participants
• Non-participants should not be allowed to create transactions
• Currencies must be limited to 120-128 chars (current DB limit)
• There should be a fallback in case the user leves the chat after tracking some transactions
• When a new user is added to the group AFTER everybody else registered it could break the bot:

• confirmation in /expense should have "Cancel" option
• it shouldn't be allowed to select participants in another user's transaction

The bot could probably just delete the messages from previous steps.
